External components setting FUSE: Fuse C1: Capacitor for input voltage smoothing C2: Capacitor for Output voltage smoothing Please make sure to use fuse 1.0A Capacitance : 3.3F to 33F Rated voltage : 250V or higher Capacitance : 47F to 470F Rated voltage : 16V or higher, Low impedance part Impedance is 0.42 max at High frequency range. Ripple current is 0.2Arms above. Impedance of capacitor affects the output ripple voltage. Capacitance : 0.1F to 0.22F Rated voltage : 250V or higher Film capacitor or ceramic capacitor. Reduce the noise terminal voltage. The constant value should be evaluated in the set. In the absolute maximum ratings, the reverse peak voltage should be 400V or higher, the average rectifying current should be 1A or higher, and the forward surge current should be 40A or higher. 10 to 22 1/4W Reduce the noise terminal voltage. The constant value should be evaluated in set. Varistor must be used. It protects this part from lightning surge and static electricity. 20 40 60 80 100 Output Current Io(mA) 120 Load Regulation -6.0 Output Voltage Vo(V) -5.0 -4.0 -3.0 -2.0 -1.0 0.0 0 20 40 60 80 100 120 140 160 Output Current Io(mA) Maximum Io=120mA Load Regulation (Ta=25C, Vi= -141V) C3: For noise terminal voltage reduction D1: Rectifier diode Surface Temperature Rising Surface Temperature Increase T(C) R1: For noise terminal voltage reduction ZNR: Varistor 40 35 30 25 20 15 10 5 0 0 Surface Temperature Increase (Ta=25C, Vi= -141V) 20 40 60 80 100 Output Current Io(mA) 120 Appendix Notes No technical content pages of this document may be reproduced in any form or transmitted by any means without prior permission of ROHM CO.,LTD.

Products listed in this document are no antiradiation design. The products listed in this document are designed to be used with ordinary electronic equipment or devices (such as audio visual equipment, office-automation equipment, communications devices, electrical appliances and electronic toys). Should you intend to use these products with equipment or devices which require an extremely high level of reliability and the malfunction of which would directly endanger human life (such as medical instruments, transportation equipment, aerospace machinery, nuclear-reactor controllers, fuel controllers and other safety devices), please be sure to consult with our sales representative in advance. It is our top priority to supply products with the utmost quality and reliability. However, there is always a chance of failure due to unexpected factors. Therefore, please take into account the derating characteristics and allow for sufficient safety features, such as extra margin, anti-flammability, and fail-safe measures when designing in order to prevent possible accidents that may result in bodily harm or fire caused by component failure. ROHM cannot be held responsible for any damages arising from the use of the products under conditions out of the range of the specifications or due to non-compliance with the NOTES specified in this catalog.
